The price-earnings ratio (P/E ratio) measures how much investors are willing to pay for each dollar of a company’s earnings. It is calculated by dividing the company’s stock price by its earnings per share (EPS).
The P/E ratio is widely used to evaluate stock valuation.
The P/E ratio helps investors determine whether a stock appears relatively expensive or inexpensive compared to its earnings.
It also helps compare companies within the same industry.
A high P/E ratio may indicate investors expect strong future growth, while a low P/E ratio may signal slower growth or undervaluation.
The P/E ratio is calculated using:
Stock Price ÷ Earnings Per Share (EPS)
For example, if a stock trades at $50 and its EPS is $5, the P/E ratio is 10.
Investors analyze the ratio relative to industry averages, historical performance, and expected earnings growth.
A technology company trading at $100 per share with earnings per share of $4 has a P/E ratio of 25.
What is considered a good P/E ratio?
It depends on the industry and growth expectations.
Can a company have a negative P/E ratio?
Yes, if the company has negative earnings.
Why do growth companies often have higher P/E ratios?
Investors may expect higher future earnings growth.
